Constructor Detail

Tabs

public Tabs()
Method Detail

getTabbox

public Tabbox getTabbox()
Returns the tabbox owns this component.

It is the same as AbstractComponent.getParent().


getWidth

public java.lang.String getWidth()
Description copied from class: HtmlBasedComponent
Returns the width. If null, the best fit is used.

Default: null.

Overrides:
getWidth in class HtmlBasedComponent

getAlign

public java.lang.String getAlign()
Returns the alignment of tab. Reserved for future extension; not supported yet.

Since:
3.0.0

setAlign

public void setAlign(java.lang.String align)
              throws WrongValueException
Sets the alignment of tab. Reserved for future extension; not supported yet.

Default: "start".

Parameters:
align - must be "start" or "center" or "end".
Throws:
WrongValueException
Since:
3.0.0

invalidate

public void invalidate()
Description copied from interface: Component
Invalidates this component by setting the dirty flag such that it will be redraw the whole content of this component and its dependences later. And, the widget associated with this component and all its descendant at the client will be deleted and recreated, too.

If the application is totally controlled by the server side (i.e., you don't write client codes), you rarely need to access this method.

It can be called only in the request-processing and event-processing phases. However, it is NOT allowed in the rendering phase.

Specified by:
invalidate in interface Component
Overrides:
invalidate in class AbstractComponent

getZclass

public java.lang.String getZclass()
Description copied from class: HtmlBasedComponent
Returns the ZK Cascading Style class(es) for this component. It usually depends on the implementation of the mold (AbstractComponent.getMold()).

Default: null (the default value depends on element).

HtmlBasedComponent.setZclass(java.lang.String)) will completely replace the default style of a component. In other words, the default style of a component is associated with the default value of HtmlBasedComponent.getZclass(). Once it is changed, the default style won't be applied at all. If you want to perform small adjustments, use HtmlBasedComponent.setSclass(java.lang.String) instead.

Overrides:
getZclass in class HtmlBasedComponent
See Also:
HtmlBasedComponent.getSclass()

beforeParentChanged

public void beforeParentChanged(Component parent)
Description copied from class: AbstractComponent
Default: does nothing.

Specified by:
beforeParentChanged in interface ComponentCtrl
Overrides:
beforeParentChanged in class AbstractComponent
Parameters:
parent - the new parent. If null, it means detachment.
See Also:
ComponentCtrl.beforeParentChanged(org.zkoss.zk.ui.Component)

beforeChildAdded

public void beforeChildAdded(Component child,
                             Component refChild)
Description copied from class: AbstractComponent
Default: does nothing.

Specified by:
beforeChildAdded in interface ComponentCtrl
Overrides:
beforeChildAdded in class AbstractComponent
Parameters:
child - the child to be added (never null).
refChild - another child component that the new child will be inserted before it. If null, the new child will be the last child.
See Also:
ComponentCtrl.beforeChildAdded(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component)

insertBefore

public boolean insertBefore(Component child,
                            Component refChild)
Description copied from interface: Component
Inserts a child before the reference child.

You could use Component.setParent(org.zkoss.zk.ui.Component) or Component.appendChild(org.zkoss.zk.ui.Component) instead of this method, unless you want to control where to put the child.

Note: Component.setParent(org.zkoss.zk.ui.Component) always calls back Component.insertBefore(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component) and/or Component.removeChild(org.zkoss.zk.ui.Component), while Component.insertBefore(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component) and Component.removeChild(org.zkoss.zk.ui.Component) always calls back Component.setParent(org.zkoss.zk.ui.Component), if the parent is changed. Thus, you don't need to override both Component.insertBefore(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component) and Component.setParent(org.zkoss.zk.ui.Component), if you want to customize the behavior.

If you would like to monitor if a component is attached or detached from a page, you could register a desktop listener implementing UiLifeCycle.

Specified by:
insertBefore in interface Component
Overrides:
insertBefore in class AbstractComponent
Parameters:
child - the new child to be inserted.
refChild - the child before which you want the new child being inserted. If null, the new child is append to the end.
Returns:
true if newChild is added successfully or moved; false if it already has the specified child and the order doesn't change.

onChildRemoved

public void onChildRemoved(Component child)
Description copied from class: AbstractComponent
Default: does nothing.

Specified by:
onChildRemoved in interface ComponentCtrl
Overrides:
onChildRemoved in class AbstractComponent
See Also:
ComponentCtrl.onChildRemoved(org.zkoss.zk.ui.Component)

onChildAdded

public void onChildAdded(Component child)
Description copied from class: AbstractComponent
Default: does nothing.

Specified by:
onChildAdded in interface ComponentCtrl
Overrides:
onChildAdded in class AbstractComponent
See Also:
ComponentCtrl.onChildAdded(org.zkoss.zk.ui.Component)

renderProperties

protected void renderProperties(ContentRenderer renderer)
                         throws java.io.IOException
Description copied from class: HtmlBasedComponent
Renders the content of this component, excluding the enclosing tags and children.

See also ZK Client-side Reference: Property Rendering

Overrides:
renderProperties in class XulElement
Throws:
java.io.IOException
